Why isn't schedutil governor available for my build x86_64

[darksky]

I built an image for my x86 box starting from:

CONFIG_TARGET_x86=y
CONFIG_TARGET_x86_64=y
CONFIG_TARGET_x86_64_DEVICE_generic=y

I am not seeing the schedutil governor for my image:

# cat /sys/devices/system/cpu/cpufreq/policy0/scaling_available_governors
performance powersave

Yet it is present in my running system's /proc/config.gz

CONFIG_CPU_FREQ_DEFAULT_GOV_SCHEDUTIL=y
CONFIG_CPU_FREQ_GOV_SCHEDUTIL=y

Seems that intel_pstate does not support that/it is legacy
